- Application August 27, 1929. No. 388,848 20mm. (01; 215 -43) Thisinvention relates to a closure and aims to provide a device of thischaracter which will present functionally and structurally improvedcharacteristics over previous articles of like nature as heretoforeprovided.

While the features of the invention may be employed in numerousdifferent associations, they are primarily intended for use inconnection with a dispensing receptacle such, for example, as an oil canor other type of container in which comparatively' small amounts of thefluid contents are to be dispensed at one time. In such association, thepresent invention aims to providela closure which will prevent theprobability of any of the contents escaping accidentally from within thecontainer, even although the closure may have been used any number oftimes.

A further object of the invention is that of providing a closure inwhich the parts may readily be operated, and in which such parts willprovide a fluid-tight seal, it being, moreover, an object to furnish aclosure embodying relatively few parts capable of being economicallymanufactured, largely by automatic machinery.

With these and further objects in mind, reference is had to the attachedsheet of drawing, illustrating one practical embodiment of theinvention, and in which:

Fig. 1 shows a pouring spout in section;

Fig. 2 is a similar viewof the cap; and

hFig. 3 shows these parts in assembled relations ip.

In these views, the numeral 5 indicates the spout, which is providedwith a pouring lip 6,

and, at the point short of such lip, is formed with a screw-thread 7.The bore 8 of this spout terminates in a preferably flared portion 9providing a valve seat, as hereinafter described. The cap includes ashell or body 10 which may be of a generally conical shape, and have arecess formed with threads 11 corresponding to the threads '7. The outerface of this up may be formed with ridge portions 12 whereby the fingersof an operator may readily grip the same, in ,order to effectuate arelative turning between the cap and the spout. Extending from within*the base of the cap recess is a plug portion 13 preferably of an areaand configuration such that it will cooperate with the seat 9.

Both the spout and cap are preferably formed of 'a, suitable metal suchthat both 'of them may be manufactured by any well known stamping orextrusion process.

Moreover, as shown, the side walls of thecap recess are preferablyinclined inwardly to eartend parallel to the correspondingly'taperedadjacent portion of the spout, and these walls present an annularflange, orridge. 14 for cooperation with the adjacent spout portion.

In closures of this type as heretofore constructed, considerabledifhculty has been experienced in that, under frequent use, it has beenfound that where cork has been employed, the latter has disintegrated,resulting in leakage. Moreover, where the pouring spout, or neck, has 65been relatively heavy, the crushing effect of the parts coming intocontact with each other-incident to the use of screw-threadshas'been sogreat that the sealing contact has been destroyed.

However, by means of the present invention, it will be observed that avalve structure is provided, first, between the stem 13 and the seat 9,and secondly, between the upper outer face portion of the spout'and theridge, or flange, 14.75 Also, in view of the fact that the nozzle is of,relatively thin' metal, the end of' the spout will, at all times,--whenthe parts are associated with each other in sealing .contacHe subjectedto both an inward and outward pressure, which will prevent a destructivecrushing but will, at all times, afford an effective seal, preventingescape on the .part of the'fluid contained within the receptaclewithwhich the sp ut is associated.

From the foregoing, it will be appreciated that, among others, theseveral objects of the invention aforenamed are achieved. It will,moreover, be understood that'numerous changes in construction, andrearrangements of the parts,

might be resorted to without departing from the 1. A closure including,in-combination, a nozzle formed with a bore, a cap.the bore of saidnozzle being of relatively: restricted .area and at least one of saidnozzle and cap elements comprising a body of relatively soft anddeformable metal, screw-threads upon said cap and nozzle for forcing theformer inwardly along the latter, a projecting portion forming a of saidcap and extending into the bore of said nozzle and tending to force thenomle walls outwardly, and confining portions forming a part of, saidcap and acting against the outer face'of said nozzle to press the sameinwardly. 4 1
